翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Winston cone ： ウィキペディア英語版 Winston cone A Winston cone is a non-imaging light collector in the shape of an off-axis parabola of revolution〔(【引用サイトリンク】title=Winston Cone )〕〔(【引用サイトリンク】title=Winston Cones for a Cylindrical WCD )〕 with a reflective inner surface. It concentrates the light passing through a relatively large entrance aperture through a smaller exit aperture.〔 The collection of incoming rays is maximized by allowing off-axis rays to make multiple reflections before reaching the exit aperture. Winston cones are used to concentrate light from a large area onto a smaller photodetector or photomultiplier. They are widely used for measurements in the far infrared portion of the electromagnetic spectrum in part because there are no suitable materials to form lenses in the range.〔 Winston cones take their name from their inventor, the physicist Roland Winston. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Winston cone」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
